Face #mask rules: compulsory coverings in shops, fines and who is exempt from wearing one
Face coverings are mandatory in shops and supermarkets, and soon-to-be in places of worship and cinemas. Here's everything you need to know
telegraph.co.uk/health-fitness…
2/6 What counts as a face covering - and what are the options?
From home-made versions crafted out of hoover bags and panty liners (yes, really) to bandanas that transform even the most genteel Home Counties shopper to roadside bandit
3/6 Surgical Masks: The most common design that everyone clambered to buy from Amazon in the early days of lockdown. Effective to a point, protecting the wearer against large droplets although not so much with airborne particles due to the loose fit.
4/7 N95 #Masks: The most effective mask in circulation (although in critically short supply). Masks take their name from their ability to screen out 95 per cent of airborne particles. Experts don't recommend the public use these masks as they are intended for healthcare workers
Cycle #Masks: The masks remain untested with regard to coronavirus & don’t have to abide by the same standards as medical equipment, so check their filters are N95 grade (or an equiv't).
They also need to be washed or have their filters changed regularly, depending on the design.
5/7 Home Made #Masks: A 2013 study by @PHE_uk
looked at the various suitability of household materials to filter bacterial and viral aerosols when used as masks. Vacuum cleaner bags seemed to be particularly good; less so, breathable materials such as 100% cotton, linen & silk.
6/7 Scarf #Mask: A recent study conducted in South Korea found that if you have Covid-19 and cough on someone from eight inches away, wearing a cotton mask will reduce the amount of virus you transmit to that person by 36 times
7/7 DIY Dusk #Mask: They provide a tight fit, which scientists say is essential for blocking out airborne particles. As with other makeshift Covid masks, people have taken to spraying them with a high-percentage alcohol spray in order to sterilise them between use.
